【Abstract】 The control process and relevant algorithm for cutting strips by flying shears are discussed and developed under conditions that the cut point of strip is positioned near the exit of the last stand of tandem cold mill(TCM). The shear knives’ position of the flying shears is controlled by the instructions sent from a cam switch which is coaxial with the motor rotor of the flying shears. The strip sections cut off by such a control procedure and relevant algorithm are proved, and the strips’ tensile between this control procedure and conventional rolling process is also given.更多还原
